We describe percutaneous repair of severe pulmonary regurgitation and a right ventricular outflow tract pseudoaneurysm in a 19-year-old patient after repair of pulmonary atresia, ventricular septal defect, and major aortopulmonary collaterals. A 3D printed model of his heart was used to simulate percutaneous repair with a closure device in the aneurysm neck and a Venus P-valve in the right ventricular outflow tract. The encouraging findings from the simulation allowed us to plan the complex procedure effectively with a successful outcome and avoidance of surgery.
